Data for Computing Extended Rasch Models

Description

Artificial data sets for computing extended Rasch models.

Usage

raschdat1
raschdat2
raschdat3
raschdat4

lltmdat1
lltmdat2

rsmdat

lrsmdat

pcmdat
pcmdat2

lpcmdat

raschdat1_RM_fitted
raschdat1_RM_plotDIF
raschdat1_RM_lrres2

Format

Numeric matrices with subjects as rows, items as columns, missing values as NA.

Details

raschdat1_RM_fitted is the resulting object of RM(raschdat1) and used in examples to reduce computation time. For the generation of raschdat1_RM_plotDIF see the excluded example code of plotDIF. raschdat1_RM_lrres2 results from LRtest(RM(raschdat1), split = "mean")
